Update: I was unfortunately not aware of Shamus Young's severe criticism of Fallout 3 available here to link in the original piece and I regret that. It dovetails rather nicely with what I've written and it's much better executed than my piece. I strongly recommend anyone...

Hints

Body armorYou can get Ballistic Armor by going to the top floor and jumping off the edge nearest the doorway. Go through there and the armor will be on the right-hand side. There are extra rockets to the left.

Easy kills
The Impulse Rifle kills in one shot anywhere on the body. To get it, go to the top floor using the middle lift and jump off the end nearest the Impulse Rifle. You should just make it. Quickly jump off there because your enemies can easily see you.
